Use Silica supplements to strengthen plant cell walls, improve plant structure and reduce transpiration rates which will allow plants to continue photosynthesis even under stressed environments. Silica also improves resistance to wilting, excess heat, and drought. Silica is recognized by the CFDA as a key element in all plant life. Normally derived from soil, Silica is a necessity for any hydroponic or soilless garden. Silica supplements can be used during all stages of growth and in multiple growing mediums such as soil, soilless, coco coir, and in hydroponic growing media like growstones or clay pebbles.
